Abstract

PURPOSE:To prevent the generation of setting abnormality caused by erroneous operation by searching for a memory means corresponding to a selected screen by a display selection means when a display screen is selected by selection operation and displaying the selected screen when the memory means is YES and cancelling a request when the memory means is NO. CONSTITUTION:When a screen number is directly inputted by a ten-key, a CPU 18 for a PMC detects input operation to store the screen number in a register and searches for the display screen memory file of a non-volatile memory 24 on the basis of the stored screen number to discriminate whether the memory region of the address corresponding to the screen number is set to zero. When 1 is set, it is meant that screen display is prohibited and, therefore, a display device 29 displays to the effect that the display of the screen of the screen number is prohibited. When zero is set, since the screen display corresponding to the inputted screen number is permitted, the CPU 18 for the PMC executes the display of the screen corresponding to the screen number.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display screen selection device for an injection molding machine.

[0002]

2. Description of the Related Art An injection molding machine has been already known in which a predetermined display screen or display items are displayed on a display device to perform an interactive operation. In general, a display screen that can be displayed on the display device is prepared as a plurality of display screens including various data setting screens and monitor display screens.
A large number of display items are displayed on each display screen. For example, as the data setting screen, there are an injection condition setting screen, a weighing condition setting screen, a sprue break condition setting screen, etc. Further, in the injection condition setting screen, injection speed switching positions and injections at each switching position are performed. Many display items such as speed, maximum injection pressure, etc. are displayed. Of course, the final interactive operation, that is, the data setting operation and the reference work of the monitor, are performed individually for each subdivided display item, but by specifying the subdivided display items from the beginning. When you try to access it, the specific work of the target becomes complicated, so the display items are classified into functions and included in a single display screen, and only the display screen that contains the necessary display items is displayed, and the target display items are displayed. After specifying, the interactive operation is performed.

[0003]

However, in the conventional injection molding machine, all the display screens and display items that can be displayed are enumerated as selection targets. As the number of display screens and display items that can be improved and increased, the task of selecting a target becomes complicated. Also, once the initial settings are made, it is possible to select items that do not need to be changed or items that you do not want a third party to change the settings. It could happen.

Therefore, an object of the present invention is to eliminate the drawbacks of the prior art and to easily call up only the display screens and display items required for the setting operation in normal work and the monitor work. Another object of the present invention is to provide a display screen selection device for an injection molding machine, which can prevent the occurrence of setting abnormality due to such a wrong operation.

[0005]

The display screen selection device of the present invention is an injection device in which a display screen displayed on the screen of the display device is selectively displayed on the display device by a predetermined selection operation to perform an interactive operation. In the molding machine, setting means for setting display availability for each of the various screens, storage means for storing the display availability set for each of the various screens,
The storage means is searched in correspondence with the screen selected by the predetermined selection operation, and if stored as yes, the selected screen is displayed on the display device, and if not stored, With the configuration characterized by including display possibility determining means for canceling the display, the required selection operation of the display screen is facilitated.

Further, in an injection molding machine in which a display screen to be displayed on the screen of the display device is selectively displayed on the display device by a selection operation by a function key to perform an interactive operation, whether or not to display is set for each screen. The same object is achieved by providing the setting means and the selection operation prohibiting means for stopping the selection function by the function key corresponding to the screen set to "no" by the setting means.

Further, in the injection molding machine in which predetermined display items are displayed on the screen of the display device and interactive operations are performed, a propriety setting means for setting display propriety for each display item displayed on the screen of the display device. And a propriety storage unit that stores propriety of display set for each item,
A configuration is provided that includes a display item selection unit that searches the availability storage unit and displays on the display device only the display items that are stored as OK, thereby facilitating an operation of selecting a required display item. I chose

[0008]

According to the present invention, whether or not display is possible for each display screen is set through the setting means and stored in the storage means, and whether or not display is possible is set by the availability setting means for each display item of each display screen and is stored in advance in the availability storage means. Remember.

When the operator selects a display screen by a predetermined selection operation, the display propriety determination means searches the storage means corresponding to the selected screen, and the storage means corresponding to the screen is stored as OK. For example, while the selected display screen is displayed on the display device, if NO is stored, the display request is canceled and the display is not executed. Further, in the configuration in which the display screen to be displayed is displayed by the selection operation by the function key, the function of the function key for displaying the screen set to NO by the setting means is automatically stopped by the operation of the selection operation prohibiting means. It As a result, the selection request itself for the display screen set to "No" by the setting unit is canceled, and like the above, only the display screen set to be displayable by the setting unit can be displayed.

When the operator selects a display screen which is allowed to be displayed, the display item selection means searches the propriety storage means corresponding to the display screen and displays only the display items stored as displayable. Display on the device.

Since the width of the selection target is limited to only the display screens and display items set to be displayable in advance, only the display screens and display items required for the setting operation in the normal work and the monitor work can be easily provided. Since it can be called and interactive operations for unnecessary items can be prohibited, setting data of items that do not need to be changed or items that you do not want a third party to change the settings can be set. Can be held safely.

FIG. 2 is a diagram showing a display example of an initial setting screen for setting whether or not to display a screen that can be displayed on the display device 29. This initial setting screen is stored in the ROM 13 as the display data of the screen number “# 0”, and the operator selects the “display screen selection” function menu from the ROM 13 by the function selection operation using a predetermined function key. It is called and displayed on the display device 29.

Here, "# 11" to "# 95" are screen numbers assigned to the screens that can be displayed on the display device 29, and "injection setting" to "servo diagnosis" are screen numbers. Corresponding to each of the screen names, each of which is classified into nine large groups "injection weighing" to "maintenance" according to their respective attributes. For example, for a large group of “injection measurement” related to injection operation, “# 11 injection setting” to
For example, the display screen of "# 14 automatic purge" is included. Needless to say, "injection weighing", "temperature",
The screen numbers included in the large groups of “mold operation”, “mold file”, and “input / output” are mainly screens related to data setting (active dialogue from the operator's side), and others "Process monitoring", "High-speed monitor", "Diagnostic alarm", "Maintenance" screen numbers are mainly those related to the monitor display (passive interactive operation from the operator's side). is there. Then, when the screen of each screen number is selected and displayed, various functions divided into more detailed units, such as data setting items (in the case of data setting screen) and monitor display items (in the case of monitor display screen) are displayed. Many are displayed. The contents of data setting items and monitor display items will be described later, and will not be described here.

When the function menu of "display screen selection" is selected by the above-described function selection operation, the initial setting screen as shown in FIG. The function allocation of u changes to that shown in FIG. 2 by the processing of the PMC CPU 18. That is, the function key p
Is assigned as a display enable setting key forming a part of the setting means, and the function key q is assigned as a display disabling setting key forming a part of the setting means. Also,
Regarding the function keys b to f, every time the function key a acting as a switching key is operated, its function is changed cyclically between the state shown in FIG. 6 and the state shown in FIG. become. The function key t functions as a setting end key by function allocation, and is related to a process related to display screen selection, that is,
This is used to return the display state of the display device 29 to the initial screen for selecting a function when the display enable / disable setting operation to be described below is completed.

Then, the operator who selects the function menu of "display screen selection" and refers to the initial setting screen as shown in FIG. 2 appropriately sets the cursor movement key to set whether or not various screens are displayed. 2 is operated, a cursor (not shown) is moved to the position of the screen name for which display availability is set on the display screen as shown in FIG. 2, and the function key p or function key q
Operate as necessary. As described above, the function key p is used to set display enabled, and the function key q is used to set display disabled. During this time, PM
The C CPU 18 constantly monitors the operating states of the cursor movement keys and the function keys p and q by the operator, and every time the function key p or q is operated, the screen number #N of the screen name where the cursor is positioned is displayed. Correspondingly, whether or not each screen can be displayed is sequentially stored in the display screen storage file of the non-volatile memory 24 serving as a storage means as shown in FIG. When the function key p is operated, the value 0 indicating that display is possible is set in the storage area DN of the address corresponding to the screen number #N of the screen name where the cursor is positioned, and when the function key q is operated. Is set to the storage area DN, which is a value 1 indicating display / non-display. For example, when the cursor is positioned on the screen name of "injection setting" and the function key p is operated, 0 is set in the storage area D11 of the display screen storage file. Then, depending on the value set in DN, the content of the message on the initial setting screen is automatically changed from "Delete" to "Display" or "Display" to "Delete" in correspondence with the screen number #N. To inform the operator of the operating status.

The operator repeatedly executes the above-described operation, sets display propriety for each screen name, and stores it in the display screen storage file of FIG. 3 provided in the non-volatile memory 24.

Further, in the case of setting whether or not to display each display item displayed on the display screen having the screen name set as displayable, the operator further performs the following operation. This operation is divided into a preparatory operation for selecting the name of the display screen on which the display propriety of the item is to be set and a substantial operation for selecting the display item to be displayed on the display screen.

Therefore, when setting whether or not to display the display items displayed on each display screen, the operator first refers to the guidance message corresponding to the function keys b to f as a preparatory operation and refers to the function keys b to f.
By operating, the name of the large group including the name of the display screen for which item display availability is set is selected, and the range of screen name selection is narrowed down.

Here, a case will be described as an example in which whether or not to display the display item displayed on the display screen of "# 83 standard selection" is set. At this stage, the guidance message as shown in FIG. 6 is displayed on the display screen of the display device 29, and the name of the large group “input / output” including “# 83 standard selection” is not displayed. Therefore, the operator operates the function key a, which serves as a switching key, once, and the function keys b to b
The function of f is changed from the state shown in FIG. 6 to the state shown in FIG. Then, along with this, the guidance message changes to the state of FIG. 7, and the name of the large group “input / output” including “# 83 standard selection” is found. Then, the operator further operates the function key d corresponding to “input / output”. Then function keys b to f
Function changes again, and a guidance message as shown in FIG. 8 is displayed on the display screen of the display device 29, that is, "external input / output" and "standard selection" among the screen names included in the large group of "input / output". The screen names of "," and "machine status" are displayed. Here, the screen name of “analog output” that should correspond to the function key c and the screen name of “indicator lamp” that should correspond to the function key e are not displayed because of the screen display enable / disable setting operation described above. Since the value 1 indicating the display failure is set in the storage area D82 of the address of the screen number # 82 and the storage area D84 of the address of the screen number # 84 in the display screen storage file, the functions of the function keys c and e are stopped. Is. It should be noted that this function does not correspond to the selection operation prohibition means, and it is not always necessary to restrict the display of the screen name based on the contents of the display screen storage file at the stage of displaying the guidance message for setting whether to display the item. Absent.

Then, as described above, the operator makes a "# 83
When the function key d corresponding to "standard selection" is operated, the PMC CPU 18 detects this operation, and the second initial setting screen as shown in FIG. 4 on the screen of the display device 29, that is, screen number "# 183". The display item selection screen of “# 81 External input / output”, “# 85” is displayed.
Machine state "... etc. and the second initial setting screen"# 111 "-corresponding to the display screens of"# 11 "-"# 95 "-
“# 195” is all prepared in advance, and these second
The initial setting screen is called by the display device 29 in accordance with the selection status of the screen name that is the setting target of whether or not to display the item. On the second initial setting screen, item names of data setting items and monitor display items that can be displayed on the display screen of the corresponding screen numbers are displayed in a list as shown in FIG. The operation up to this point is the preparation operation.

Further, instead of such a preparatory operation, a second initial setting screen corresponding to a desired screen name may be directly selected and displayed by a numerical value input operation using the ten keys of the display device 29. The value obtained by adding 100 to the screen number of the desired screen name is the screen number of the corresponding second initial setting screen. For example, 1 in 83 in the above example.
The display state of FIG. 4 can be realized by adding 00 and entering "# 183" on the ten-key pad.

Then, when the calling of the second initial setting screen is completed, the functions of the function keys b to f change again to return to the state of FIG. 6 or 7. The operation for setting the display propriety of each item on the second initial setting screen is the same as the above-described display propriety setting operation for the display screen. That is, in the second initial setting screen of FIG. 4, the cursor movement key is appropriately operated to move the cursor to the position of the item name for which display availability is set, and the function key p, which is a part of the availability setting means. Alternatively, the function key q is operated as necessary to store the display propriety of each item in the display item storage file of the non-volatile memory 24 serving as the propriety storage means in correspondence with the item number K of the item name where the cursor is located. Let it be done (see Fig. 5). Similar to the second initial setting screen, the display item storage files are provided in a required number in a one-to-one correspondence with the display screens of “# 11” to “# 95”. As a result, for example, “# 183” is displayed. If the cursor is placed on the item name of "Ejector operation when the front gate is open" of item number 1 while the second initial setting screen of "" is displayed and the function key p is operated, "# 83" will be displayed. 0 is set in the storage area E1 corresponding to the item number 1 of the display screen storage file provided corresponding to the screen. Also,
As in the case of the display enable / disable setting operation on the display screen, depending on the value set in EK (display enable = 0, display disable = 1), the message content on the second initial setting screen corresponds to item number K. It automatically switches from “Delete” to “Display” or from “Display” to “Delete” to inform the operator of the operating status.

The operator repeatedly executes the above-described operation to set whether or not to display each item name, and then, as shown in FIG.
The display item storage file as shown in FIG.

Further, when switching the display screens for which the display propriety of items is to be set, as described above, the preparatory operation using the functions of the function keys b to f is executed again, or the numerical value from the numeric keypad is used. The second initial setting screen corresponding to the desired display screen is directly selected by input, and thereafter, the item permission / prohibition setting operation similar to the above is repeatedly executed.

The second initial setting screen is called up in FIG.
If the function key t as the end key is operated in such a display state, the display of the display device 29 returns to the initial setting screen of FIG. 2 again, but the functions of the function keys b to f are used again on the initial setting screen. By performing a preparation operation, it is possible to perform an operation of setting the propriety of a display item relating to a desired display screen. This function is convenient because the screen number of the original display screen can be easily searched when the second initial setting screen of the desired display screen is directly selected by numerical input from the ten keys. Further, when returning to the state of FIG. 2, it is also possible to perform the display enable / disable setting operation of various display screens in the same manner as described above. On the other hand, if the function key t is operated in the state where the initial setting screen as shown in FIG. 2 is displayed, the PMC CPU 18 detects this operation as an operation for ending the display enable / disable setting operation, and the display device 29 displays. Returns the display state to the initial screen for function selection. Further, there is no restriction on the operation of calling the second initial setting screen by inputting a numerical value from the ten keys, and the operation can be executed regardless of the display state of the display device 29. The initial setting screen can be called by always pressing the "# 0" numeric keypad.

The operator who has completed the processing relating to the display screen and the setting of the propriety of the display item is indicated by the function key t.
Is operated to return the display state of the display device 29 to the initial screen for function selection.

Only the guidance message of the function key shown in FIG. 6 or 7 is displayed on the display device 29 in the initial screen selection state. Each time the function key a, which functions as a switching key, is operated once, a guidance message is displayed as shown in FIG.
The point of cyclic change between the state shown in (1) and (2) is the same as the case described above. However, the function of each function key is not for selecting the screen name to set whether to display the item, but for displaying the screen for data setting and performing the interactive operation regarding the setting, or the monitor screen. Is displayed to return to the original function for performing interactive operations such as monitoring and confirmation operations. The interactive operation using these function keys can be performed both during drive control of the injection molding machine 30 and when the injection molding machine 30 is in a non-operating state.

Therefore, the operator may change or correct the data setting of various molding conditions, or confirm the graph display by the sampling data of the injection pressure or the holding pressure of the injection molding work currently performed, if necessary. The desired display screen is selected by operating the function keys as appropriate.

Here, an example will be described in which the setting screen of the standard selection function, that is, the display screen of "# 83 standard selection" is selected to change the setting of the standard selection function. Since the name of the large group including the screen name of "# 83 standard selection" is "input / output", the operator first operates the function key a once to perform the same function as in the case of the item permission / prohibition setting operation described above. The function assignment of the keys is changed to the state shown in FIG. 7, and the function key d corresponding to “input / output” is operated, and the function keys b to f
The function of is changed to display the guidance message as shown in FIG. 8 on the display screen of the display device 29.

At this time, only three types of screen names of "external input / output", "standard selection", and "machine status" out of the large groups of "input / output" are displayed as the guidance message. The display screen set as display disabled by the setting screen, that is, the screen names of "analog output" and "indicator lamp" in which 1 is set in the storage area of the corresponding address of the display screen storage file is not displayed as a guidance message. , At the same time, "analog output",
The selection function by the function keys c and e corresponding to the screen name of "indicator light" is automatically stopped. Therefore,
For example, even if the function keys c and e are operated, the display screens related to "analog output" and "indicator lamp" are not called up by the display device 29, and naturally, they correspond to the screen names of "analog output" and "indicator lamp". It is also impossible to add an operation such as a setting change to the setting items provided by the user. This function is a function corresponding to the selection operation prohibiting means, and is convenient when protecting the data contents of the setting screen where the careless execution of the setting change operation is not desired.

Next, the operator who refers to the guidance message as shown in FIG. 8 operates the function key d corresponding to the display screen of "# 83 standard selection" which is the target of the setting change work. Then, the PMC CPU 18 as the display item selection means detects this operation as a screen selection operation for interactive operation, searches the display item storage file of the non-volatile memory 24 corresponding to the selected screen name, and displays it. Only the display items that are set to "Yes" are displayed on the screen of the display device 29 as shown in FIG. Therefore, when the setting operation as shown in FIG. 4 is performed during the item permission / prohibition setting operation, the item numbers 4, 6, 8 and
The setting items 9 and 11 are out of display contrast. Of course, it is not possible to change the setting of a setting item that is out of display contrast, which is convenient for protecting the data content of the setting item that is unfavorable to the careless execution of the setting change operation. As shown in FIG. 11, on the setting screen of the standard selection function, the setting operation for all setting items is "... do / ...
It is a two-choice system of "No" or "Simple ... / Standard ...", and the operator operates the cursor movement keys as necessary to select the item name for which the setting is desired to be changed, Further, by operating the function key p or q, which is assigned a function as a selection key for two alternatives,
Appropriate setting change operation is performed for any item for which setting change is allowed. In the example of FIG. 11, the operator can easily identify the selection state of the setting for each item based on the presence or absence of an underline on the screen. When the function key a, which is assigned a function as a switching key, is operated after the necessary setting change work, the screen of the display device 29 returns to the state shown in FIG. 6 or 7, and the function assignment of the function key is also performed. Return to the original state. At the same time, the selection status of the settings for each item,
For example, selection data such as “permit / disallow” is stored in the non-volatile memory 24 in correspondence with the screen number and the item number.

The same applies to the case of selecting another setting screen and performing the setting change operation. The name of the large group is selected by the function key and the screen name (however, display Is allowed) and a desired setting screen is selected, so that an appropriate setting change operation is performed. In the example of FIG. 11, the case where the setting change operation is performed by the two-choice method has been described. However, in the data setting screen belonging to a large group such as “injection weighing”, “temperature”, and “mold operation”, the numerical value by the numeric keypad is used. Generally, setting data is determined by input. Further, there are some data setting screens for injection speed, injection pressure, etc. in which the waveforms of speed and pressure are set. In either case, the final setting data corresponds to the screen number and item number and is nonvolatile. The data is stored in the sex memory 24.

Also, when the screen name of the monitor display screen is selected and a passive interactive operation such as monitoring and confirmation is performed, the same as above, the PMC CPU as the display item selecting means.
Reference numeral 18 searches the display item storage file of the non-volatile memory 24 corresponding to the selected screen name, and displays only the monitor data and the graph of the display item set to be displayable. Depending on the situation, if only necessary monitor data and graphs are set as displayable items, the problem that the monitor data and graphs are complicated and difficult to see can be solved.

When a screen for data setting is displayed or a monitor screen is displayed, the screen number # ... Is directly input by the ten-key pad, as in the case of setting permission / prohibition of the display screen and display items. A desired display screen can be selected. FIG. 9 and FIG. 10 show the PMC CP as the display availability determination means and the display item selection means at that time.
It is a flow chart which shows an outline of processing which U18 performs.

When the screen number # ... is directly entered on the ten-key pad, the PMC CPU 18 as the display availability determination means
First, this input operation is detected in the discrimination processing of step a1 shown in FIG. 9, and the screen number is temporarily stored in the register N (step a2). Then, the PMC CPU 18 searches the display screen storage file of the non-volatile memory 24 based on the value of the screen number N stored in the register, and whether 0 is set in the storage area DN of the address corresponding to the screen number N. It is determined whether or not (step a3). If 1 is set in the storage area DN, it means that the display of the screen corresponding to the input screen number N is prohibited.
The PMC CPU 18 displays a message indicating that the display of the screen of screen number N is prohibited on the display device 29, for example, "The screen of the entered number cannot be displayed." (Step a5), and again the new display is made. It returns to the standby state waiting for the input of a different screen number. In the operation of selecting the display screen by inputting the screen number on the ten-key pad, the guidance message as shown in FIG. 8 indicating whether or not the screen can be displayed is not displayed.
There is a possibility that the screen number set as display prohibited may be erroneously input, but by performing the determination processing in step a3, an error that the screen set as display prohibited is displayed indefinitely occurs. It is supposed to be prevented.

On the other hand, if 0 is set in the storage area DN, it means that the display of the screen corresponding to the input screen number N is permitted, and therefore the PMC CPU 18
Executes the display of the screen corresponding to screen number N,
The display process of step a4 is executed.

FIG. 10 shows details of the display processing in step a4. CPU 18 for PMC that started the display process
First, the index K for searching the item number is initialized to 0 (step b1), and whether the current value of the index K has reached the item number Kmax of the display items determined corresponding to the screen number N or not. Is determined (step b2). If the screen number is # 83, the value of Kmax is 13, as is apparent from FIGS. 4 and 5. If the current value of the index K does not reach the number of items Kmax, the PMC CPU 18 determines the index K.
Is incremented by 1 (step b3), and it is determined whether 0 is set in the storage area EK at the address K of the display item storage file corresponding to the screen number N (step b4).

As described above, the display item storage file corresponding to the screen number N is, in short, a file in which data is set by the item availability setting operation using the second initial setting screen corresponding to the screen number N. The file stores information regarding whether or not each display item on the screen of screen number N can be displayed.

Therefore, if 1 is set in the storage area EK, it means that the display of the Kth display item on the display screen corresponding to the screen number N is prohibited, so P
The MC CPU 18 does not execute the process of step b5 related to the item display and detects the storage area EK in which 0 indicating that the display is possible is stored, or the value of the index K is K.
Until the maximum value is reached, step b2 is performed as described above.
~ The process of step b4 is repeatedly executed.

When the storage area EK in which 0 is stored is detected during the repeated execution of such processing, the PMC CPU 18 determines, at each time, based on the current value of the index K at that time. The contents of the Kth display item stored corresponding to the display screen of screen number N, for example,
"Ejector operation when front gate is open ... Permitted and not permitted" is read from the ROM 13 and displayed on the display screen of the display device 29 (step b5).

Hereinafter, the PMC CPU 18 repeatedly executes the same processing as described above until the value of the index K reaches Kmax, and all the display screens of the screen number N are set to be displayable. Display contents of item 2
No. 9 is displayed on the display screen, and the process related to the screen display ends. Note that FIG. 11 shows a display example when the screen number “# 83” is numerically input under the setting conditions as shown in FIGS. 4 and 5.

After the display processing as shown in FIG. 10 is completed, the PMC CPU 18 displays the setting data (when the data setting screen is selected), the monitor data and the graph display according to the selected screen number. (When the monitor display screen is selected) and the like are performed, but this point is the same as the conventional one. For example, when the screen number “# 83” is selected, the PMC CPU 18 further sets the setting state of each item, that is, “permit / deny” or “simple” after the display process of FIG. 10 is completed. The setting state such as "/ standard" is stored in the nonvolatile memory 24 for each item corresponding to the screen number.
Read from and draw an underline on either one of the two choices according to the setting situation,
The setting state at that time is shown to the operator. Naturally, in the case of the setting screen for setting data using numerical values, the numerical values set at that time are displayed corresponding to the display items, and when the monitor screen is selected, it is set to be displayable. Only monitor data and graphs corresponding to the display items will be displayed.

Further, when the initial setting screen as shown in FIG. 2 and the second initial setting screen as shown in FIG. 4 are displayed and the setting contents are changed, a password and other password means may be used together. In this case, careless setting change operation can be prevented more reliably.

[0051]

The display screen selection device for an injection molding machine according to the present invention sets whether or not to display each screen in advance,
Since only the display screen set as displayable is displayed on the display device according to a predetermined selection operation,
Even if there are a large number of screens that can be displayed, it is possible to easily select the desired display screen and display it on the display device by setting only the display screens that are required for normal interactive operations to be displayable. You can In addition, display items displayed on each screen, such as data setting items and monitor display items, can be set in advance to be displayed or not, so it is necessary to change the settings once initial settings are made. It is possible to prohibit the display of setting items that do not exist or the setting items that the third party does not want the setting to be changed by a third party, and it is possible to prevent the setting abnormality caused by an erroneous operation or the like. Moreover, since the types and the number of monitor display items displayed on the same display screen can be limited as necessary, complicated display can be avoided and an easy-to-see monitor display can be realized.
